General operating system performance mainly related to the main problems are: Processor usage, memory footprint, disk i/0 operations, and network traffic.To view Windows performance, in most cases through Windows Task Manager, you can eject task Manager by typing: taskmgr in the command line. Task Manager can view: CPU usage, memory usage, and
developed to assist in TCP Parameter Optimization, but here we do not want to study the TCP Window Scale and maximum segment length, because this is not the focus of our current discussion. However, when testing a high-throughput AP, you may find it necessary to tune TCP parameters so that you can get a larger throughput on each iPerf client-For details, see DrTCP.

Encountering performance bottlenecks, the system is being dragged down, which is no doubt the administrator does not want to see the situation. Starting with Windows Vista, Microsoft has stepped up its monitoring of the performance of the system's resources, the main technical means of the so-called performance counters. Using these counters, we can
